SAN JOSE, Calif.—(BUSINESS WIRE)—March 7, 2005—
Chrontel (
www.chrontel.com), a leading provider of video
interface technologies, is announcing two new DVI (Digital Visual
Interface) transmitters, the CH7312 and CH7313, which support HDCP
(High-bandwidth Digital Content Protection) and comply with Intel's
SDVO (Serial Digital Video Output) PC interface specification. The
CH7312 device was revealed at the Intel Developer's Forum (IDF) in San
Francisco on March 2, the first public demonstration of a
SDVO-compliant DVI/HDCP transmitter IC.

DVI/HDCP transmitters are mixed-signal ICs that transmit
copy-protected video pixel data over a secure link from PCs to
external displays. With these devices, consumers will be able to watch
copy-protected high-definition content on PC displays, LCD monitors,
video projectors or HDTVs equipped with a DVI/HDCP receiver.

DVI/HDCP transmitters accept RGB video data from a graphic
controller on the CPU motherboard of a PC, and convert the video data
for secure transmission to an external DVI-compliant display using
HDCP content protection to authenticate the license of the receiving
display device. Video data is then encrypted for transmission to the
properly licensed DVI/HDCP receiver. Content creators and owners, such
as movie studios and musicians, can confidently release digital
content for PC playback if it is protected by robust and secure
authentication and transmission schemes like HDCP.

The SDVO interface specification is a high-speed serial data
interface designed into Intel's latest PCI Express-enabled chipsets:
the Intel(R) 915G, 915GV, 910GL and 945G Express Chipsets.
Manufacturers that design PCs using PCI Express will require
SDVO-compliant DVI/HDCP transmitters to link the internal Integrated
Graphic Device of a PCI Express chipset with external displays that
use the popular DVI/HDCP standard to receive and display
high-definition video content.

"As PCs increasingly become the media hubs of the modern home, it
is critically important that they support robust content protection
standards like HDCP," explained Dr. David Soo, Chrontel president and
CEO. "As a leading vendor of DVI solutions to the global PC industry,
Chrontel placed a high priority on offering cost-effective DVI devices
that support HDCP encryption/authentication and Intel's new SDVO
interface specification."

Chrontel's new CH7312 and CH7313 transmitters support the 1G-2Gbps
high-speed video input rate of the SDVO interface specification. Both
Chrontel devices support video output rates up to 165 Mpixels/second,
suitable for driving high-definition external monitors and displays
with resolutions up to UXGA (1600 x 1200 pixels) at a 60Hz refresh
rate. The CH7312 uses an external device to store the HDCP
authentication and encryption key. The CH7313 incorporates an internal
HDCP key.

"Intel believes the SDVO and HDCP technologies are important for
advancing the utility of PCs for consumers," said Sunil Kumar, Intel's
Director of Chipset and Software Marketing. "We are pleased that
Chrontel is moving quickly to adopt the SDVO interface for their new
DVI/HDCP transmitters."

The mixed-signal CH7312 and CH7313 are the latest in a family of
SDVO-compliant devices that Chrontel began releasing in 2004. Chrontel
offers the most complete line of SDVO-compliant video interface
devices, including LVDS and DVI transmitters plus standard and
high-definition TV transmitters.

Pricing and Availability

The Chrontel CH7312 and CH7313 will be sampling in 2Q05, and
production volumes will be available early 3Q05. The devices are
offered in low-cost 48-pin LQFP packages, and come complete with
Windows driver support.

The CH7312 is priced at $3.75 in 10,000 piece quantities. The
CH7313, with an internal key, is priced at $4.00 in 10,000 piece
quantities.
